Some off-list questions reminded me that I never followed up properly on this one. The machine is now in service and runs cooler and quieter than the aging (P4) Fujitsu-Siemens it replaced.
My only complaint is that due to the maze of twisty nonsense that is the HPE web site I never got the BIOS upgrade, but it doesn't seem to matter much in our context. The machine runs well, and I upgraded it to the latest snapshot just over half an hour ago. dmesg: OpenBSD 6.0-current (GENERIC.MP) #1: Fri Dec 2 00:32:07 MST 2016 bu...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC.MP cpu0: Intel(R) Celeron(R) CPU G1610T @ 2.30GHz ("GenuineIntel" 686-class) 2.30 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE,NXE,LONG,SSE3,PCLMUL,DTES64,MWAIT,DS-CPL,VMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,PCID,SSE4.1,SSE4.2,POPCNT,DEADLINE,XSAVE,LAHF,PERF,ITSC,FSGSBASE,SMEP,ERMS,SENSOR,ARAT real mem = 4057341952 (3869MB) avail mem = 3966910464 (3783MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: date 12/31/99, BIOS32 rev. 0 @ 0xf0000, SMBIOS rev. 2.7 @ 0xf3bdb000 (64 entries) bios0: vendor HP version "J06" date 07/16/2015 bios0: HP ProLiant MicroServer Gen8 acpi0 at bios0: rev 2 acpi0: sleep states S0 S4 S5 acpi0: tables DSDT FACP SPCR MCFG HPET FFFF SPMI ERST APIC FFFF BERT HEST FFFF FFFF SSDT SSDT SSDT SSDT SSDT acpi0: wakeup devices PCI0(S4) acpitimer0 at acpi0: 3579545 Hz, 24 bits acpimcfg0 at acpi0 addr 0xf4000000, bus 0-63 acpihpet0 at acpi0: 14318179 Hz acpimadt0 at acpi0 addr 0xfee00000: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) mtrr: Pentium Pro MTRR support, 10 var ranges, 88 fixed ranges cpu0: apic clock running at 99MHz cpu0: mwait min=64, max=64, C-substates=0.2.1.1, IBE cpu1 at mainbus0: apid 2 (application processor) cpu1: Intel(R) Celeron(R) CPU G1610T @ 2.30GHz ("GenuineIntel" 686-class) 2.30 GHz cpu1: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE,NXE,LONG,SSE3,PCLMUL,DTES64,MWAIT,DS-CPL,VMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,PCID,SSE4.1,SSE4.2,POPCNT,DEADLINE,XSAVE,LAHF,PERF,ITSC,FSGSBASE,SMEP,ERMS,SENSOR,ARAT ioapic0 at mainbus0: apid 8 pa 0xfec00000, version 20, 24 pins acpiprt0 at acpi0: bus 13 (IPT1) acpiprt1 at acpi0: bus -1 (IPT2) acpiprt2 at acpi0: bus -1 (IPT3) acpiprt3 at acpi0: bus -1 (IPT4) acpiprt4 at acpi0: bus 3 (IPT5) acpiprt5 at acpi0: bus -1 (IPT6) acpiprt6 at acpi0: bus 4 (IPT7) acpiprt7 at acpi0: bus 1 (IPT8) acpiprt8 at acpi0: bus 7 (PT02) acpiprt9 at acpi0: bus -1 (PT03) acpiprt10 at acpi0: bus 2 (PT05) acpiprt11 at acpi0: bus 0 (PCI0) acpicpu0 at acpi0: C2(350@96 mwait.1@0x20), C1(1000@1 mwait.1) acpicpu1 at acpi0: C2(350@96 mwait.1@0x20), C1(1000@1 mwait.1) acpitz0 at acpi0: critical temperature is 31 degC "IPI0001" at acpi0 not configured "PNP0A06" at acpi0 not configured "PNP0303" at acpi0 not configured "PNP0F13" at acpi0 not configured "ACPI000D" at acpi0 not configured bios0: ROM list: 0xc0000/0x8000 0xc8000/0x4000!
